Linux: how to kill all running processes of a user using his/her userid

Question

One user has several processes running on a shared machine. I want to kill all running processes of the user. What Linux command should I use to kill processes using his/her user id?

Answer 1

You can use pkill or killall command to kill all processes of a user. When you run these commands, the user will be logged out and all his/her processes will be killed.

E.g.

$ pkill -U UID

$ pkill -u UID

$ killall -u USERNAME
